[ovs-discuss] Re : ip_gre_mod.ko module

[DarkBls]

I try to make a GRE tunnel between two OvS on two server (phosphorus and sulphur):

I assume that I need two tunnels, one on each OvS isntance:

On Phosphorus:

ovs-vsctl --db=tcp:192.168.93.201:1977 create interface name=gre0 type=gre options:remote_ip=192.168.93.204
e29c391b-2e07-4a2e-95de-99cf6f23158d
ovs-vsctl --db=tcp:192.168.93.201:1977 create port name=gre0 interfaces=[e29c391b-2e07-4a2e-95de-99cf6f23158d]
01c689e2-ecab-4ee6-8902-6aba2efe2deb
ovs-vsctl --db=tcp:192.168.93.201:1977 add bridge br0 ports 01c689e2-ecab-4ee6-8902-6aba2efe2deb


[root at Phosphorus ~]# ovs-vsctl --db=tcp:192.168.93.201:1977 list-ports br0
gre0
tap0

On sulphur:

ovs-vsctl --db=tcp:192.168.93.201:1978 del-port br0 eth1
ovs-vsctl --db=tcp:192.168.93.201:1978 create interface name=gre0 type=gre options:remote_ip=192.168.93.203
8e21e4d9-09e6-46be-85b1-7fe80cb64614
ovs-vsctl --db=tcp:192.168.93.201:1978 create port name=gre0 interfaces=[8e21e4d9-09e6-46be-85b1-7fe80cb64614]
50d15acb-7081-4ee3-8384-72248910b051
ovs-vsctl --db=tcp:192.168.93.201:1978 add bridge br0 ports 50d15acb-7081-4ee3-8384-72248910b051

[root at Sulphur ~]# ovs-vsctl --db=tcp:192.168.93.201:1978 list-ports br0
gre0
tap0


I try to send an arping through tap0 but it doesn't work.

I must have missed something since I don't see any port 47 opened on any server

If you are using a 1.0.x release or later, you no longer need to load a separate GRE kernel module.  A new virtual port interface was added to the openvswitch kernel module, and GRE is now implemented through that.  Are you seeing some sort of problem?
